"I'm a rice farmer, not a fisherman," he sighs, tugging at the net. "But my field has been completely flooded for the past two months. So I fish in my courtyard."

Widespread flooding has killed at least 56 people in Niger since the rainy season began in June, and left over 180,000 homeless, according to the interior ministry.

In one of the world's poorest countries, where most houses are made of earth or mud, flooding has destroyed thousands of homes.

"I used to have two houses, both of which collapsed with the rain," Soumana told the Thomson Reuters Foundation, as he tried to untangle a couple of small fish from his net, with his children looking on.

But now "I have nothing to house or feed my family, other than fish," he said.

"EXTRAORDINARY" RAINFALL

Soumana's situation is far from uncommon. For Nigeriens unable to afford cement homes, each rainy season increasingly brings a dangerous ordeal, local experts say.

According to Katiellou Lawan Gaptia, head of meteorology at Niger's Met Office, climate change in the Sahel is creating warmer conditions where the atmosphere can hold more moisture, often increasing the volume of rainfall.

"This year's rain is just extraordinary," he said. "In Niamey alone, the season's rainfall has increased by 84 percent since 2010."

Gabagoura, a village northwest of Niamey, is one of the worst affected areas by the recent floods.

On the median strip of the main road, mats and foam mattresses dry on guardrails. Around them, piles of wood and straw are all that are left of more than 290 homes that collapsed at the end of August, leaving 1,200 people homeless.

Village chief Adamou Saley walks towards a massive silk-cotton tree, under which 15 people have taken shelter.

"Look at this misery – total desolation," he said, looking around at the remnants of homes.

Hadjara Yacouba's house was entirely destroyed by the rains. "We have nothing, not even a tent," she said, lowering her eyes.

"I am a widow with 17 children, and we have lost everything."

EARLY WARNING

Before the start of the rainy season, the government advised people living in flood-prone areas to leave their homes before the rains began, said Boubakar Sidiko, secretary general for Niger's Ministry of Humanitarian Action and Disaster Management.

But few heeded the advice "because they refused to abandon their homes or had nowhere else to go", he said.

Saley said Gabagoura village had indeed been warned by the government on television and radio.

"But the village was spared the brunt of flooding last year, so people thought they would be safe," said the village chief.

Some still tried to build drainage gutters around their homes, but even they collapsed, he added.

Fatima Alher, who heads a project mapping flood-prone zones in Niamey, thinks national and local efforts to prepare for flooding were "not enough".

"To date we've not had an efficient system to alert the entire population," she said. "Flood survivors we spoke to said they weren't properly informed of what was happening."

Saley said the government and several non-governmental organisations had sent food and supplies, and some flood victims had moved into the village's two schools.

"But some people are still left on the streets," he said.

School is set to start again in early October, which may mean those sheltering in schools will need to find a new place to stay.

"If we don't get any more help I don't know what will happen to those currently living in the school," Saley said.

Officials at the Ministry of Humanitarian Action and Disaster Management say it has identified four potential shelter areas in Niamey, but has yet to set them up due to a lack of funding.

"As soon as we have the funds to prepare the shelter sites we will do so," Sidiko said.

"We believe the shelters will allow us to temporarily house all those currently left in schools," he added, without specifying how many people the sites could accommodate.

In the meantime, Saley worries about more predicted rainfall. "Eighty percent of us are without homes. If it rains again, we'll lose the entire village," he said.
